Feature Interview: Herman Pontzer

It may seem unfair that some people can eat anything without putting on weight, get by on just a few hours sleep and age ever so gracefully. It's just biology and the science of adaptation says Dr Herman Pontzer, a professor of evolutionary anthropology at Duke University. Dr Pontzer invites us to embrace human diversity and focus on how and why we differ as a way to better understand how our bodies work so we can all stay healthy. His new book is called Adaptable: How Your Unique Body Really Works and Why Our Biology Unites Us. He joins Jesse.
